Remember the Daleks, Doctor Who's cybernetic villains? And the Cybermen, Doctor Who's other cybernetic villains? Of course you do. But soon you'll be uttering the name Tritovore in the same breath as those world-shattering villains. Doctor Who's Easter special will introduce these new monsters, which are described as half-man, half-fly. A BBC source told Digital Spy:

They are disgusting and will last long in the memory... Everyone remembers the Daleks and the Cyberman, but not a lot else if they're honest. The Tritovore will change that. Scriptwriters are confident they'll make a huge impact.

And the Tritovore may come back in future episodes as well. I have to say, if you want to create a menace we'll be naming for years to come, including the word "Trite" in their name probably isn't the best move. [Digital Spy]
